Tokyo’s core CPI excluding food and energy eased to 1.6% year on year in May, down from 1.9% previously. The reading points to softer underlying price pressures in the capital.
The slowdown in the ex food and energy measure follows recent moderation in inflation dynamics, with the annual rate slipping by 0.3 percentage points from the prior period. Markets will parse the data for signals on the momentum of Japan’s disinflation trend.
Implications For Monetary Policy And Currency Markets
The slowdown in Tokyo’s core inflation to 1.6% significantly reduces the pressure on the Bank of Japan to implement another interest rate hike in the coming months. This data suggests that achieving a stable 2% inflation target remains a challenge, reinforcing a cautious monetary policy stance. We believe this will keep Japanese government bond yields suppressed for the foreseeable future.
This reinforces the primary driver for a weaker yen, which is the massive interest rate differential between Japan and other major economies like the United States. With the U.S. Federal Reserve funds rate holding firm at 5.50% and Japan’s at just 0.1%, the incentive to sell yen for higher-yielding currencies remains incredibly strong. We are therefore looking at USD/JPY call options or futures positions, targeting a move back towards the 160 level that triggered intervention concerns in 2024.
Equity Market Tailwinds And Intervention Risks
For equity traders, a weaker yen is a direct tailwind for Japan’s export-heavy Nikkei 225 index. Corporate profits, which hit a record high last quarter according to the Ministry of Finance, will see a further boost as overseas earnings are translated into more yen. We view this as a clear signal to add to long positions in Nikkei 225 futures.
The main risk to these positions is direct currency intervention by the Ministry of Finance, which spent a record 9.8 trillion yen in April and May of 2024 to defend the currency. Given this history, implied volatility in yen currency pairs is likely to rise as USD/JPY climbs. Buying straddles or strangles on USD/JPY could be an effective strategy to profit from a large move, regardless of whether it’s a continued upward drift or a sharp reversal caused by intervention.
